850W Fully Modular ATX Supply

This fully modular ATX power supply delivers 850W from a single +12V rail. It targets builders who want a compact 150mm unit with native 16-pin support for modern graphics cards. Japanese main capacitors and a hydraulic bearing fan aim for long-term reliability.

PCIe 5.0 16-Pin Connector Limits

The included native 16-pin cable is rated for 600W output to a PCIe Gen 5.0 graphics card. Four 6+2-pin PCIe connectors and eight SATA power connectors handle additional components. The single-rail design simplifies power distribution across all cables.

80 Plus Gold Efficiency Headroom

At typical load the unit reaches 90% efficiency under the 80 Plus Gold programme. Active PFC maintains a power factor above .9 across the 100-240V input range. Six protection circuits guard against over-voltage, over-power, short-circuit, under-voltage, over-current and over-temperature conditions.

Questions about this item

Which version of this PSU should I pick for a build that needs a native 16-pin cable?

The GP-UD850GM PG5 includes a high-quality native 16-pin cable rated for 600W output, so this single model covers PCIe 5.0 graphics cards without extra adapters.

What does the 850W rating deliver in a real system?

A single +12V rail provides the full 850W to components, while 80 Plus Gold certification means 90% efficiency at typical load, reducing waste heat and electricity cost.

How does the PCIe 5.0 interface affect the power limit on the 16-pin connector?

The supplied 16-pin cable is specified for 600W, which is the practical ceiling for a PCIe 5.0 graphics card connected to this unit.
